Massive Monster Mayhem is a Canadian game show television program that combines live-action and computer-generated imagery animated elements.

It features live gameplay by kids in futuristic challenges against gigantic Monster Superstars for the chance to win prizes and save the planet from destruction.

In each episode, Master Mayhem would send one of his Monster Superstars down to Earth to cause havoc which would result in the players fighting them in the Mashdown.

Factory Kids signed a deal with DHX Media to secure the North American DVD rights to Massive Monster Mayhem.
